PRESSURE BEGULATOR.

Application filed April 15, 1922. Serial No. !553,300.

water pipe lines or for any other fluid, gas

or the like, and has for its object to provide a diaphragm actuated lever controlling a circuit maker and breaker against the action of a spring, said circuit maker and breaker being adapted to be in circuit with a starting and stopping device, for instance a pump starting 'and stop-ping device, thereby stopp-ing the pump when the pressure in the pipe line rses above a predetermined amount.

A further object is to provide a pressure controlled circuit maker and breaker, said circuit maker and breaker comprising a pivoted lever 'actuated by a diaphragmaganst the action of a spring, said "pivoted lever having pivoted adjacent its free end a roller supported arm the roller of which engages a guide bar, a switch controlled arm pivoted to the guide bar beneath the roller and connected to the roller arm by means of a spring, the pivotal point of which is adapted to-pass behind the spring whereby said spring will hold the switch controlling'lever in a circuit making or breaking position according to the position of the diaphragm.

With the above and other objects in View the invention resides in the combination and arrangement of parts as herenafter set forth, shown in the drawings, described and claimed, it being understood that changes n the precise embodiment of the inventon may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsz- Figure 1 is a vertical longitudinal sectional view through the pressure regulator.

Figure 2 is a horizontal sectional view taken on line 2 -2 of Figure 1.

Figure 3 is a side elevaton of the device,

parts being broken away to better show the structure. v

Figure 4 is a sectional view through the device taken on line4--4 of F igure 1.

Referring to the drawings, the numeral 1 designates the casing of the pressure regulator and 2 a removable bottom Secured thereto by means of screws 3. Pivotally mounted between ears 4: extending upwardly from the bottom 2 is an upwardly exten'ding controlling lever 5, which lever is provided with a horizontally disposed arm 6 which overlies and receives in a recess 7' thereof upwardly extending lug 8 carried by a plate 9 whch rests on the diaphragm 10. The' diaphragm 10 may be formed from heavy rubber or from any other material and s disposed in the chamber 11 formed in the under side ot' the bottom 2 and in the upper side of the removable diaphragm holdng plate 12. The diaphragm plate 12 is provided with a thread'ed opening 13 in which may be threaded a pipe which may lead to the pipe line orto a receptacle in which pressure is being regulated, thereby allowing pressure to engage the underside ofthe diaphragm 10 and force the same upwardly thereby rocking the lever 5 in the direction of the arrow a, Figure l. Connected to the 'upper end of the lever 5 is a coiled spring 14, the end 15 of which is connected to an adjust-ing screw 16 which extends through the side wall 17 of 'a casing 1, and by means of which adjusting screw, the pressure necessary to rock the lever 5 in the direction of the arrow a may be varied thereby allowing the regulator to be adjusted for different pressures to be overcome by the upward movement of the diaphragm.

The casing 1 is provided with removable side plates 18, which are connected together by means of a transversely disposedbolt 19, which extends through the casing 1, thereby allowing ready access to the interior of the casing 1 for repair purposes. Pivotally connected adj acent the free end of the lever 1 at 20 is an outwardly extending arm 21, which arm 'has pivotally mounted in a bifurcaton thereof a flanged guide wheel 22 which rolls on a. fixed guiding arm 23. Pivoted to the guiding arm 23 at 24 is a downwardly extending arm 25 with the lower end of which is pivota-llv connected at 30 the lower end ing arm 25.

of coiled springs 31, said coiled sprngs having their upper ends connected at 32 to a transversely disposed pin 33, forming the pivot for the flanged wheel 22. lt will be seen that when the diaphragm is forced upwardly by an excess pressure within the pipe line or receptacle, the lever 5 will be rocked in the direction of the arrow a, there- *by stretching the spring 24. During the movement of the lever 5 in the direction ot the arrow a, the wheel 22 moves in the direc tion of the arrow a on the guide member 23 and when the wheel passes a vertical position above the pivotal point 24, the downwardly extending pivoted arm 25 will` be rocked in the direction f the'arrow b by the coiled springs 31, thereby causing an outward movement on the arm 34: in' the direction of the arrow e, which arm is formed from insulating material and is pivota-lly connected at'35 to the downwardly extend- `When the arm 34: moves in the direction of the arrow c, the pivoted contact forming member 36, which is pivotally connected at 37 to a conductor plate 38, and at 39 to the arm 34: is moved out of engagement with the contact members 40, thereby breaking the circuit 41 which may control a motor 42, which motor may opera-te a pump or other machinery for creating pressure within the pipe line or receptacle. The limit of movement of the arm 25 in the direction of the arrow b may be adjusted by the stop screw 43, which cooperates with the bevelled surface 4:4: carried by the inner end of the guide arm 23.

From the above it will be seen that an automatic pressure regulating devce is provided, which is simple in Construction and one wherein the circuit is opened and closed according to the adjustment of the device through the medium of the adjusting screw 16 and coiled spring 14:.

The invention having been set forth what is claimed as new and useful is z 1. A pressure controlled circuit maker and breaker, said i circuit maker and brealrer comprising a casing, a diaphragm carried by said casin'g, a lever pivoted in said casingand with said lever the. diaphragm cooperates for rocking the same spring means connected to the free end ot the lever for regulating the premure necessary to operate the circuit maker and breaker, a horizontally disposedguide bar adjacent the free end of the lever, an arm pivoted to the lever and overlying the guide bar, a wheel carried by said arm and engaging the guide bar, a downwardly extending pivoted lever carried by the guide bar, springs connected to the lower end of the' downwardly extending lever, the upper ends of said springs being connected to the pivoted arm adjacent the center of the wheel, a horizontally disposed zontally disposed arm.

a ar/ao arm carried by the downwardly extending arm and a switch controlledby said hori- 2. l`he combination with a diaphragm operated pivoted lever of a pressure controlled circuit maker and breaker, of an adjustable spring means connected to the free end of said lever, said lever being substantially vertically disposed, a horizontally dispose d pivoted arm carried adjacent the free end of said lever and pivoted thereto, a fianged roller pivoted to the arm, said roller engaging a guide bar which is horizontally disposed, a pivoted arm extendin the guide bar, an ad ustable member for limting the movement of the downwardly extending pivoted arm, a switch controlling lever, an outwardly extending horizontally disposecl arm connected to the switch .controlling lever and the downwardly extending arm, and springs connectng the lower end of the downwardly extending arm to the r outer end of the horizontally disposed arm carried by the pivoted lever.

3. A pressure controlled circuit maker and breaker comprising a casing, a pivoted lever, a diap-hragm cooperating with said lever, a tension spring connected to the lever, means for varying the tension of said spring, a guide bar adj acent one side of said lever, an arm pivoted to the lever and overlying the guide bar, a wheel carried by said arm and engaging one side of the guide bar, an arm pivoted to the guide bar and extending in the opposite directions to the wheel, means for limiting the movement of said last named arm, spring means connecting the free end of the last named arm and the arm carrying .the wheel and adapted to pass to' opposite sides of the pivotal point of the last named arm, and a switch controlling arm controlled by the last named arm.

4. The combination with a diaphragm controlled lever of a circuit ma-ker and breaker, said lever being actuated againstthe action of a spring, of a switch lever controlling 'mechanism, said mechanism comprising'an arm pivoted to the lever, a guide bar, a wheel carried by said arm and engaging the guide bar, an arm pivoted to the guide bar and extending away from the wheel, a spring connecting the lever carried pivoted arm and the guide bar pivoted arm, and a link connection between the guide bar pivoted arm and the switch controlling lever.
